A heat pipe is located within the center of the body and portions of the passageway are disposed about the heat pipe. A resistance heating band is mounted on the body to conduct heat therethrough to heat the heat pipe. The heat pipe serves to heat plastic flowing through the surrounding passageway portions to the outlet.
